Q: What is included in Welink Tech's Cloud Service?

The Cloud Service provides centralized multi-tenant management for your routers via Cradlepoint NetCloud or Peplink InControl. It delivers remote policy enforcement, real-time data consumption analytics, firmware patch automation, and 24/7 NOC oversight.

Q: How do you secure cellular data streams?

We apply a triple-layer defense: hardware-accelerated AES-256 site-to-site VPN tunnels, Private APN routing to bypass the public internet entirely, and managed NGFW firewalls with live Deep Packet Inspection (DPI).

Q: What is the difference between a site-to-site VPN and a Private APN?

A VPN (IPSec/WireGuard) encrypts traffic over the public Internet between two endpoints. A Private APN isolates traffic directly at the mobile carrier's core network before it ever hits the internet. Private APNs are recommended for payment cards (PCI-DSS); VPNs connect remote branches to corporate headquarters (ERP, file shares).

Q: Is your VPN solution compatible with our corporate firewalls?

Yes. Our configurations natively integrate with Fortinet FortiGate, Palo Alto Networks, Sophos XG, Cisco ASA, and Check Point appliances, supporting AES-256-GCM encryption and Perfect Forward Secrecy (PFS).

Q: What SLA is guaranteed for Premium Services?

A contractual 99.9% uptime availability SLA (< 43 minutes downtime/month). Includes proactive NOC monitoring, 4-hour on-site hardware dispatch, and monthly availability reporting.

Q: Which telemetry metrics does your NOC monitor 24/7?

Radio metrics (RSRP, RSRQ, SINR), uplink/downlink throughput, ping latency, packet jitter, per-SIM data consumption, IPSec VPN tunnel state, router CPU/RAM load, and firewall threat alerts. Every anomaly triggers an automated alert and NOC escalation.

Maximize network performance and secure every byte traversing your 4G/5G links. AES-256 encrypted VPN, private APN, managed Deep Packet Inspection firewall, intelligent QoS, and 24/7 NOC oversight.

Our premium services upgrade standard cellular links into carrier-grade conduits compliant with PCI-DSS, HDS, and GDPR cybersecurity mandates.

The Stakes

Why securing your 4G/5G cellular links is mandatory

By default, cellular connections route over the public Internet. Without a cryptographic defense layer, confidential assets—payment streams, ERP credentials, sensitive emails—face the exact same risks as an open hotel Wi-Fi.

Cybersecurity agencies report that cyberattacks targeting mid-market businesses rose by 54% in 2024. MitM exploits on unencrypted cellular lines take advantage of public IP routing vulnerabilities.

That is why Welink Tech implements an enterprise defense-in-depth architecture across 3 key pillars: encryption (VPN), network isolation (Private APN), and inspection (Managed Firewall).

pest_control

Man-in-the-Middle Attacks

On an unencrypted line, malicious actors intercept passwords, ERP sessions, and unmasked payment data in cleartext.

bug_report

Data Exfiltration

Without a DPI firewall, malware can exfiltrate customer databases or financial ledgers to foreign servers without triggering alerts.

gavel

Regulatory Non-Compliance

Failing to isolate and encrypt traffic violates PCI-DSS, HDS, and GDPR mandates, exposing businesses to severe regulatory fines.

dns

Public IP Exposure

Cellular routers with exposed public IPs are constantly targeted by botnet crawlers. Unprotected ports serve as instant attack vectors.

Security Stack

The 6 Pillars of Our Premium Offering

Each capability can be activated individually or layered into a comprehensive defense-in-depth architecture.

vpn_lock

Site-to-Site IPSec/WireGuard VPN

AES-256-GCM encrypted tunnels with Perfect Forward Secrecy. Compatible with Fortinet, Palo Alto, Sophos, Cisco, and Check Point. Built-in WAN optimization.

sim_card

Private APN: Isolated Network

Complete traffic isolation starting directly at the carrier base station via GRE or MPLS tunnels. Traffic never touches the public internet. Required for PCI-DSS.

local_fire_department

Managed NGFW Firewall + DPI

Real-time Deep Packet Inspection, application filtering, IP geo-blocking, IPS/IDS, and URL filtering. Threat signatures updated autonomously.

speed

Advanced DSCP Quality of Service

Granular traffic queuing: VoIP on DSCP EF (absolute priority), payment card terminals on DSCP AF (high priority), guest Wi-Fi best-effort.

monitoring

24/7 Premium NOC Supervision

Continuous telemetry: RSRP/RSRQ, throughput, latency, jitter, packet loss, VPN tunnel health, router CPU load. Automated incident dispatch in < 15 min.

analytics

Reporting & Analytics

Post-deployment performance audit: traffic bandwidth curves, peak hours, unique client sessions, VLAN usage breakdown, and actionable optimization advice.

Architecture

The 5 Welink Defense Layers

Network Isolation: Private APN

Traffic is isolated right at the cellular cell tower. Data never traverses public IP space. The foundation of secure cellular IT.

Encryption: AES-256 VPN Tunnel

Even within private APNs, AES-256 encryption renders all packets undecipherable in the event of hardware or physical interception.

Filtering: NGFW Firewall + DPI

Live inspection of every packet. Blocks known intrusion attempts (IPS), anomalous behavior (heuristics), and malicious URLs.

Prioritization: DSCP QoS

Bandwidth classification by service type. Critical workloads (VoIP, POS, ERP) are never throttled by guest browsing traffic.

Supervision: 24/7 NOC Telemetry

Continuous tracking of all network telemetry parameters. Proactive threshold alerting and automated failover routing.
